How to enable backlit keyboard on a laptop
The first step is to determine the availability of the backlit keyboard on your laptop. If it exists, the process consists in pressing a special key combination. Every manufacturer in this case, assigns your button, but it sure is among the keys of the top row F1-F12. They can see the special characters printed in a different color (usually blue or red).
